To all whom it may concern:

Be it known that we, HARRY Y. Nonwooo and FREDERICK W. STALKER, both of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Recording Apparatus; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked. thereon.

Our invention has to do with recording apparatus and more particularly with mechanlsms of the type employed in making periodical records of temperature or other conditions, as generally accomplished through the aid of a time mechanism, and the present purpose is to afford a simple structure suitable for obtaining records on flat sheets, such as disks of paper or the like. A further object of the improvement is to afford novel marking instrumentalities, that permit the use of a ribon held fiatwise and out of engagement with the record sheet, with provision for always retaining the ribbon spaced from the record sheet except at the single point where a record is made. Further purposes of the invention reside in making it possible to readily position a record sheet in the machine and also in preventing damage to the machine through accidental shortcircuiting when the time mechanism is run down. To these-and other ends the invention consists in certain improvements and comblnations of parts. all as Wlll be herein- Figure 1 is a plan view of an apparatus constructed in accordance with the present invention;

Fig. 2 is a side elevation of the same;

Fig. 3 is a sectional view on the line 33 of Fig. 1, and with the marking in- Y. strumentalities idle;

Fig. 11 is a plan view of the entire apparatus in operating relation with the cover of the casing in open position, and

Fig. 12 is a sectional view on the line 12 -l2 of Fig. 11.

Similar reference numerals in the several figures indicate the same parts.

In the present embodiment of the improvement, which is intended primarilyas an illustration of one possible means for carrying out the invention, and in no sense as limiting the scope of the improvement to the particular mechanism set forth, 1 designates a housing or casing containing a cover 2 that is hinged, and a wall or partition 3 separating the casing into two compartments, one of which houses the cells 4 of the battery and the other of which houses the time and recording mechanisms that will now be described.

The 'clock mechanism Which will be more fully described presently, includes a shaft or arbor 5 which constitutes the carrier upon which the record support is mounted, the latter being designated at 6. The record support comprises a disk of metal or other suitable material, and is held in place on the carrier 5 through the instrumentality of a sleeve 7 engaging a 'beveled shoulder 8, and a wedge nut 9 that engages a beveled shoulder 10 on the sleeve 7 ,-as shown in Fig. 3. 11 designates sharpened points or projections on the support which serve to hold the record sheet or;;- disk of paper or other suitable material in place, and it Will be observed that when the parts are in operating relation the record sheet is inverted,

that is to say, is located on the under side of the support, the recording instrumentalities being also on the under side of the support and operating upwardlv to efl'ect a record,-, as will appear more fully hereinafter.

The recording mechanism comprises an actuator having a pair of spaced arms 12 fixed on a spindle 13 pivotally mounted in bearings carried by the spring standards 14.

A dependent arm ig. 2) fixed to spindle 13 carries an armature 15 which cooperates with the electromagnet 16, and actuator arms 12 are provided at their ends with an operating rod or bar 17 which engages the impression member to eflect marking on the record sheet. The actuator also carries a ribbon frame, and to this end, the bar 17'has secured thereto by means of rivets 18 a frame designated generally at 19, which is formed of spring metal or the like to permit relative movement between the end portions of the ribbon frame and the actuator, as shown in Fig. 4. The ends of the ribbon frame are designated by 20, as shown in Fig.

5, and provided at their edges with feet or projections 21, afl'ording therebetween a recess for the ribbon 22, which is preferably 20 of any suitable inked material. When the ribbon frame is forced toward the record sheet, thelatter is engaged by the feet or projections 21, while the ribbon 22- is sufii ciently spaced from the record sheet to prevent its coming in contact therewith except at a single point where the impression is made. In other words, the ribbon is prevented from smudging or blurring the record by being held away from the sheet 80 through the projections 21, as shown clearly in Figs. 4 and 5. The ribbon 22 is held upon the ribbon framein the manner shown in Figs. 4 and 6, preferably by means of a spring 23 connecting plates 24 which are at-- tached to the ends of the ribbon. The ribbon frame is attached to the bar 17 at its central portion only, as designated by the securing rivets 18 already referred to, and as a result of this, when the ribbon frame is brought into engagement with the record sheet on its support, further movement of the actuator bar 17 is permitted by a relative movement between it and the ribbon frame, whereby the bar 17 is moved far enough to force the impression member, now to be described,

against the ribbon, and move the latter against the record sheet at the point of record, as shown in Fig. 4.

v The impression member is'designated generally at 25, being pivotally mounted for swinging movement 'about a vertical axis,

and controlled in such swinging movement by any suitable means, such for instance as a temperature controlled expansion and contract-ion coil 26 to which it is connected as shown in Fig. 1. By this means, the impression member 25 is caused to have a lat- ,eral movement, or a movement longitudinally of the ribbon frame, depending upon the variations of temperature or other condition to be recorded, and the width of the inked ribbon is suflicient to permit of making a record at any point in the arc of movement of'the impression member. The latter carries at its outer end an operating portion ,with the temperature. 28 designates a stationary indicator located in the arc of travel of the operating portion 27 of the im ression member, and cooperating with an indicator 29 upon the upper side of the support 6, already referred to, and as shown in Fig. 11. The indicator 29 is located on the support 6 in a position corresponding to an indicator 30 on the reverse side of the support, and which cooperates with the paper record sheet or disk 31..

The object of this construction is to insure repositioning the record sheet at the proper point after its removal from the apparatus for any purpose. To illustrate this, if the record sheet has been removed when it is repositioned in the machine, it is set upon its support so that the indicator 30 points to the proper time when it is repositioned. The record sheet support is inverted when placed in the machine so that it is not visible from the upper side, but by positioning the support so that the indicator 29, see Fig. 11, corresponds or coincides with the indicator 28, the parts will be in proper position for commencing the operation. 32 designates a pivoted bail or handle on the support 6, for readily removing or positioning the latter. The electromagnet 16 already referred to is energized at predetermined intervals for operating the actuator, through a clock mechanism which periodically opens and closes the electric circuit that includes conductors 33 and 34 leading from the battery already mentioned to the electromagnet 16 through a switch 33*. The latter closes 11 preferably every fifteen minutes by being moved toward a switch member or circuit closer 34' mounted upon the minute arbor of the clock mechanism. The switch-33 is pivoted at 36 and carries an arm 37 which 1 lies in the path of a four-lobed cam wheel 38 mounted upon the hour arbor or spindle of the clock mechanism. The four lobes 38 permit the switch 33 to rock about its axis every fifteen minutes and at this interval to be in such condition as to be engaged by the switch 34. on the/minute arbor, which rotates once every minute. When contact is made between the terminals 33 and 34 every fifteen minutes or at any'other interval that may be selected by changingthe cam wheel on the hour arbor 39, the electromagnet 16 is energized and a record is made on the record sheet, showing the position of the impression member or temperature con 30 trolled arm at the particular moment when the circuit is closed. It is desirable that means be provided to prevent the electromagnet circuit from remaining closed when the clock mechanism is run down, and to this end means are employed for automatically opening the circuit when the operation of the clock mechanism is stopped from exhaustion of the spring. This is preferably accomplished by mounting a single tooth 40 upon the winding arbor 41 and arranging a pinion 42 to engage said tooth. The pinion open until the spring of the clock mechanism=is rewound. The pinion 42 is so related to the tooth 40 that it is moved through the distance of two teeth for every revolution of the winding arbor 41, although tliis particular structure may be varied in different ways without changing the ultimate result of opening the main controlling circuit when the clock mechanism spring is unwound.

The mechanism herein disclosed is used to considerable extent upon refrigerator cars, as a consequence of which it is desirable to provide meansfor holding the cells 4 of the battery, in rigid relation in the easing, and preventing their vibration. With this in view we employ a block 46 that is recessed to receive the ends of the cells, while 47 designates a yoke that engages the side of the cells 4, as shown in Fig. 11. The yoke 47 is carried by a pair of spring arms 48 which are pivotally mounted at 49, and when swung downwardly, engage under shoulders or latches 50 and serve to hold the cells rigidly in position. By springing the free ends of the arms 48 toward each other they arereleased from the shoulders 50, and the yoke 47 can then be swung upwardly about the pivot 49 to permit removal of the cells.

In order to secure a plurality of records, two or more record sheets may be employed with a carbon sheet 51 between them, as shown in Fig. 9, and by utilizing a flat support and flat record sheet, it is possible to secure several duplications of the record, as accurately as the original, owing to the arrangement of the fiat ribbon and cooperat= ing impression member.

We claim as our invention:

1."In a time controlled recording apparatus, the combination-with a movable flat support for a record sheet, of a marking ribbon supported in spaced relation to the support, an impression member movable to different positions over the ribbon in accord ance Withvari tions in the condition to be recorded, and an actuator upon which the ribbon is carried, the actuator, being movable independently of the ribbon and operating intermittently to move the impression menb ber against the ribbon to cause the latter to engage and mark a record sheet on the support.
